Abstract
The U.S. Geological Survey is investigating:the potential for implementation of several
Aquifer Storage Recovery systems on the Charleston,
South Carolina, peninsula. A pilot study, conducted in the Santee Limestone Black Mingo aquifer during 1993-95, indicated that the recovery efficiency, based on the national drinking-water standard for chloride, varied between 38 and 61 percent during nine Aquifer
Storage Recovery cycles. A second study, initiated in
1998 at a site in downtown Charleston, is evaluating the
geochemical and hydrologic effects of storing potable
water in the aquifer for 1 to 6 months. reliminary
results from cycles with 1-month storage periods
indicate recovery efficiencies as great as 81 percent. Decreased transport time from the production well to
observation wells has been observed, indicating a
probable increase in the permeability of the aquifer.
Analysis and geochemical modeling of water-quality data collected from the site wells are planned to
determine the dominant geo-chemical reactions, taking place during Aquifer Storage Recovery cycling in the aquifer.
